The Cowboys’ other option to replace Leary is rookie La’el Collins, who was inactive for the season opener.

“There’ll be a competition between those guys [Bernadeau and Collins] this week if Ron is not able to go,” coach Jason Garrett said. “We’ll determine by week’s end who is going to play and what the rotation might be.”

Leary is hoping to be cleared to play by then. He missed the Arizona game in 2014 when he strained the other groin, the only game he hasn’t started in three seasons with the Cowboys.

Leary said this injury is not as severe as the one that sidelined him last year.

“I think it was a little worse last year,” Leary said. “It’s a game time decision, but I feel good right now. It’s getting better every day. I was able to do some running around today, so I’m ahead of schedule already.”
